Specification of Letters Patent.

Patented July 1'7, 1906.

Application filed September 9, 1905. Serial "No. 277,690.

To all whom it may concern:

Be it known that I, AMELIA P. EIOHHORN, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements in Oisterns, of which the following is a specification.

My invention pertains to cisterns, and more particularly to means for preventing mosquitos and other insects and dirt an other foreign substances from gaining access to the interior of a cistern, and its utility and practical advantages will be fully understood from the following description and claim when taken in connection with the accompanying drawings, forming part of this specification, in which Figure 1. is a sectional view of so much of a cistern as is necessary to illustrate the improvements constituting the present and preferred embodiment of my invention. Fig 2 is a top plan view of the same.

Similar letters designate corresponding parts in both of the views of the drawings, referrin to which A is t e body of a cistern, which may be of masonry, as shown, wood, or other material suitable to the purpose.

B B are conduits, preferably spouts, designed to lead from eaves-troughs or other sources of supply, and O is my novel guard for excluding mosquitos and other insects and dirt from the interior of the body A, with a view of avoiding pollution of the water.

The guard O comprises a receptacle a, preferably of sheet metal, arranged in the upper end of the body A and having an opening I) and also having an outwardly-extending flange c, disposed on the edge of said body A, and a screen d, controlling the said opening I) and having for its purpose to exclude mosquitos and dirt from the interior of the body A, while permitting water to freely pass from the receptacle a to said body A. The said screen (1 is preferably of reticulated material and disposed below and riveted or otherwise fixedly connected to the receptacle a, as shown.

In addition to the features mentioned the guard C is provided with a preferably detachable overflow-conduit e, which leads from the side of the receptacle a and is designed to discharge into a down-pipe f. This pipe f may when but a single cistern is employed lead to any suitable point of discharge. When, however, two cisterns are employed, one above the other, I prefer to utilize the pipe f as the feed-pipe of the lower cistern. Also in such event I prefer to employa screen m, of reticulated or other suitable material, at the inner end of the conduit 0, where the same communicates with the interior of the receptacle (1. This screen m has for its function to prevent dirt, mosquitos, &c., from passing with the water to the lower cistern. The said screen m is detachable with the conduit c in order to permit of the guard being readily cleared of collected sediment and debris when necessary.

In the practical use of my improvements the water is discharged by the troughs B into the receptacle a of the guard C, from whence it passes to the interior of the body A. The foreign substances in the water, as well as mosquitos and other insects, are effectually prevented by the guard from entering the cistern-body and are caught in said guard.

When it is necessary to clean the guard, the same may be readily accomplished by removing the conduit 6 and screen m and wash ing the guard.

twill be gathered from the foregoing that my novel guard is simple and inexpensive in construction and is calculated to last quite as long as the body of an ordinary cistern.

I-Iaving described my invention, what I claim, and desire to secure by Letters Patent,

In a cistern, the combination with a body; of a guard comprising a receptacle arranged in the upper end of the body and having an opening in its bottom, a screen controlling AMELIA P. EIGHHORN.
